LATE NEWS PRINTING DEVICE Original Filed Aug. 22. 1930 [Illmil Patented Oct. 18, 1932 UNITED STATES PATENT OFFICE oscAn CHARLES RQE'SEN, on BROOKLYN, NEW YORK, AssIGIv'oR o Woo]: n wsman MACHINERY conPoRATI'oN, on NEW YORK, N. Y., A CORPORATION or VIRGINIA LATE Nnws rnnr'rnve DEVICE Application filed August 22, 1930,861'1211 No. 476,996. Renewed. March 31, 1932.

The principal object of this invention is to provide an impression cylinder for a late news printing couple which can be changed readily and in a very simple manner to adapt it for printing when the press is being run either collect or straight.

The invention also involves improvements in the impression cylinder by wh ch by the use of a single blanket the impresslon can be 13 made either on each revolution of the type cylinder when the press is running straight or on alternate revolutions of the type cylinder when running collect and simple and practicable means for holding a movable sleeve in either of two POSltlOIlS w1th out having the fastening means come n position under the blanket in either position. 7

Other objects and advantages of the 1nvention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which 0 Fig. 1 is a plan of the impression cyhnder of a late news printing device embodying the features of this invention;

Fig. 2 is a plan of the same showlng the other position in which the late news device can be located, and

Figs. 3-, 4 and 5 are sectional views on the lines 33, 44 and 55 respectively of F lgs. 1 and 2, Fig. 3 showing the printing couple and Figs. 4 and 5 only the impression cylinder.

As is well known it has been found practical in the printing of large metropolitan daily newspapers to use a late news device or fudge in which type may be easily set up after the forms are locked up. A space or spaces are left on the stereotype plates of the regular printing device, leaving blank spaces on the sheet and this late IIGWSdBVICG prints 7 the late news in the blank spaces. These late news devices are built with the type cylinder half the diameter of the regular type cylinder and half the diameter of the impression cylinder of the late news device. In this case the device is shown as having two sleeves late news couple will print on each of two identical sheets ordinarily printed by the regular press. This is for straight printing. However, when the press is run collect consecutive sheets produced by the main printing couple are not identical and that kind of printing will not do because late news insertionshave to be printed only on alternate sheets.

This inventionhas to do with means for providing an arrangement whereby the change can be made so as to print the late news either at each revolution of the late news type cylinder when the press is run straight or on alternate revolutions When the press is run collect.

In the form of the invention shown in the drawing a late news cylinder 1 is carried by hearings in the press frames and driven in cooperation with the late news type cylinder from any convenient shaft of the press at the proper speed ratio. 7

The impression cylinder of the latenews I 3 and 4 slidably mounted thereon and fixed as regards rotation by keys 5 and 6. These two sleeves can be'moved along thesekeysj and will rotate positively with the cylinder in all positions. A pair of locating rings 7 and 8 are provided for each one of these sleeves.

These rings are secured to the cylinder and undercut on their inner surfaces to receive a projecting portion 13 of the sleeve and limit the mot-ion of the sleeve. The undercut arrangement is to hold the sleeve firmly against centrifugal force. p V v The sleeves are held in position by clamping screws 9 for clamping each sleeve to the cylinder positively against movement from either one of the two positions in which each sleeve is placed. It will be noted that tapped holes are provided in the cylinder for receiving the clamping screws 9 and so placed that the clamping screws will not come underneath the impression blanket 10 in either position. Half of the length of each sleeve 3 or 4 is a complete annular or cylindrical ring while the other half is semi-cylindrical as indicated by Figs. 4 and 5.

Around each of the sleeves is located an impression blanket 10, this blanket being approximately half of the length of the sleeve in width. The impression blankets are mounted in the usual manner with a pawl 14. and ratchet 15 on a shaft 16 adapted to be turned up by hand by a wrench on the square end of the shaft for tightening the blanket. Each blanket is located in a definite position along the length of the impression cylinder to cooperate with the type cylinder 2 so that the printing is applied always in the same place in the columns 11 and 12 shown in Fig. 2 on the web.

In the position shown in Fig. 1 the sleeve 3 is brought u against the ring 8 and therefore the blan :et is located on the semi-circular portion of this sleeve as shown in Fig. 4. During half of the revolution of the impression cylinder the blanket will not engage the type cylinder. Therefore the web is pressed between the type and impression cylinders only on alternate revolutions of the former. This arrangement is used when running collect.

IVhen it is desired to use the late news device on a straight run and thus print on'every page of the web, the impression blanket is released by means of the ratchet device and the sleeve 3 moved away from the position shown in Fig. 1 and over against the ring 7. This is the position shown at the right of Fig. 2 with the sleeve 4 located as just de scribed.

It will be noted that the blanket is not moved longitudinally but it is again tightened up on the complete annular or circular portion of the sleeve. Now the blanket cooperates with the type cylinder to print at each revolution. This position is shown by the sleeve 4 in Fig. 5.

This is a very simple device for increasing or decreasing the working diameter of half of the circumference of the cylinder so that the late news device will print either on consecutive or alternate pages.

Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims.

Therefore I do not wish to be limited in this respect but what I do claim is 1. In a printing device, the combination with an impression cylinder having a portion of its surface of complete annular shape and another portion of less than cylindrical shape and an impression blanket adapted to be placed on either portion of said cylinder.

2. In a late news device, the combination of a rotary cylinder, a sleeve mounted on said cylinder having a portion of its surface of a complete annular shape and another portion of fractional cylindrical shape and a blanket adapted to be applied to either l portion to give a complete cylindrical impression surface or a fraction of a cylindrical impression surface and means for securing the blanket in position on either part of said sleeve.

3. In a late news device, the combination with a cylinder, of a sleeve slidably keyed thereto and capable of being moved back and forth longitudinally but rotatable with the cylinder,'said sleeve having a complete annular portion and a semi-cylindrical portion of substantially equal width, and a printers blanket located in fixed position along thev cylinder and adapted to engage either of said portions of the sleeve.

4:. In a'late news device, the combination with a cylinder, of a sleeve slidably keyed thereto and capable of moving back and forth longitudinally but rotatable with the cylinder, said sleeve having a complete annular portion and a semi-cylindrical portion of substantially equal width, a printers blanket adapted to engage either of said portions of the sleeve in accordance with the position of the sleeve, and a pair of rings fixed to the cylinder to limit the motion of the sleeve in either direction, said rings having undercut recesses to receive projections on the rings to counteract centrifugal force.

5. In an impression cylinder for a late news device, the combination with the cylinder, of a sleeve longitudinally movable there on having a complete cylindrical portion and a semi-cylindrical portion of substantially equal width, an impression blanket adapted to cooperate with either of said portions of the sleeve in accordance with the position of the sleeve along the cylinder, said sleeve being provided with a fastening device extending through it into the cylinder and means whereby said fastening device will be inserted through the portion of the sleeve which is uncovered by said blanket.

6. In a late news printing couple, the combination with an impression cylinder and a type cylinder, the impression cylinder being twice the diameter of the type cylinder, of a longitudinally movable member on the type cylinder having two portions, one of cylindrical shape and one semi-cylindrical and both twice the diameter of the type cylinder, and means whereby the impression can be taken upon either of saidportions and an imprint made at each revolution of the type cylinder or at each alternate revolution of the type cylinder.

7. In a late news printing couple, the combination with an impression cylinder and a type cylinder, the impression cylinder be- OSCAR CHARLES ROESENi
